Abstract

In a food processing line, the equipment which is likely to fragment on breakage contains magnetically susceptible particles which are separated from the food by a magnetic separation stage. When the equipment is a starch carrying tray, the moulding mix contains 5-50% of magnetic filler, such as magnetite. Reinforcement with glass fibre and jute fibre modifies the compositions for moulding the trays. Moulding mixes based on polypropylene and thermosetting resins are described. A processing line using starch trays has a conveyor for food items and a conveyor for the starch in which the food items are moulded. Both have magnetic separators.

Claims (17)

1. A method of separating fragments following breakage of equipment in a food processing line, wherein the equipment is made from a plastic moulding composition which contains magnetic particles capable of separation by magnetic separation, comprising exposing the food contaminated with fragments to a magnetic separator stage and recovering the food free of contamination.
2. A method as claimed in Claim 1, including conveying the food using a dry carrier material and exposing the dry carrier material for the food to a magnetic separation stage.
3. A method as claimed in Claim 2, wherein the food is confectionery and the dry carrier material is starch.
4. A method as claimed in any one of Claims 1-3, wherein magnetic separation is preceded by a physical separation in order to exclude coarse fragments of predetermined dimensions.
5. A method as claimed in Claim 3 or 4, wherein the starch drops between an array of tube magnets.
6. A method as claimed in Claim 3, 4 or 5, wherein the food items move past a plate magnet.
7. A plastic moulding composition inter alia for equipment in a food processing line, comprising a moulding mix and one or more fillers, one of which renders breakage fragments of equipment manufactured from the mix, separable by a magnet from material which is not separable by a magnetic field.
8. A moulding composition as claimed in Claim 7, wherein the magnetic filler includes a magnetisable metal, its alloy, its ferrites, or its oxides in particulate form.
9. A moulding composition as claimed in Claim 7 or 8, comprising magnetisable filler 5-50%, moulding polymer 15-35% and fibro reinforcement 15-35%.
10. A moulding composition as claimed in any one of Claims 7, 8 or 9, wherein the magnetic filler is magnetite.
11. A moulding composition as claimed in Claim 10, wherein the concentration of magnetite is 220-550g/l.
12. A moulding composition as claimed in Claim 10 or 11, wherein the mean particle size 20-50µ.
13. A moulding composition as claimed in any one of Claims 9-12, wherein the fibre is mineral or vegetable fibre.
14. A moulding composition as claimed in any one of the Examples.
15. Manufactured articles when moulded from a moulding composition as claimed in any one of Claims 7-14.
16. A manufactured article as claimed in Claim 15, wherein the article is a starch tray for confectionery items.
17. A manufactured article as claimed in Claim 15, wherein the article is a conveyor bucket, conveyor roller, equipment housing, or conveyor guide.
